Structures And Practices Enabling Staff Nurses To Control Their Practice, Marlene Kramer, Claudia Schmalenberg, Patricia Maguire, Linda Chmielewski Aug 2008

Structures And Practices Enabling Staff Nurses To Control Their Practice, Marlene Kramer, Claudia Schmalenberg, Patricia Maguire, Linda Chmielewski

Articles

This mixed-methods study uses interviews, participant observations, and the CWEQII empowerment tool to identify structures and attributes of structures that promote control over nursing practice (CNP). Nearly 3,000 staff nurses completed the Essentials of Magnetism (EOM), an instrument that measures CNP, one of the eight staff nurse-identified essential attributes of a productive work environment. Strategic sampling is used to identify 101 high CNP-scoring clinical units in 8 high-EOM scoring magnet hospitals. In addition to 446 staff nurses, managers, and physicians on these high-scoring units, chief nursing officers, chief operating officers, and representatives from other professional departments are interviewed; participant observations …


Evaluation Of The Xpert Methicillin-Resistant Staphylococcus Aureus (Mrsa) Assay Using The Genexpert Real-Time Pcr Platform For Rapid Detection Of Mrsa From Screening Specimens., Celine M. Herra Aug 2008

Evaluation Of The Xpert Methicillin-Resistant Staphylococcus Aureus (Mrsa) Assay Using The Genexpert Real-Time Pcr Platform For Rapid Detection Of Mrsa From Screening Specimens., Celine M. Herra

Articles

The need for rapid methods to accurately detect methicillin-resistant Staphylococcus aureus (MRSA) is widely acknowledged, and a number of molecular assays are commercially available. This study evaluated the Xpert MRSA assay, which is run on the GeneXpert real-time PCR platform (Cepheid) for use in a clinical laboratory. The following parameters were investigated: (i) the limits of detection (LoDs) for four MRSA strains; (ii) the ability to detect isolates of MRSA from a collection representative of MRSA in Ireland since 1974 (n 114) and the ability to detect control strains with staphylococcal cassette chromosome mec types IVa (IV.1.1.1), IVb (IV.2.1.1), IVc …


Rampart Roads In The Peat Lands Of Ireland: Genesis, Development And Current Performance, Juan Pablo Osorio, Eric R. Farrell, Brendan C. O'Kelly, Tom Casey Aug 2008

Rampart Roads In The Peat Lands Of Ireland: Genesis, Development And Current Performance, Juan Pablo Osorio, Eric R. Farrell, Brendan C. O'Kelly, Tom Casey

Articles

The construction and improvement of roads on peat lands has always been a challenging task in geotechnical engineering. Rampart roads, which are a particular feature of the bog roads in Ireland, are caused by the excavation of peat from the roadsides over many years for use as a domestic fuel. The historical development of rampart roads and current performance under the added traffic loading is discussed. Various road improvement methods have been applied to improve the road ability to carry traffic and the technical aspects and performance of the methods are discussed. In particular, the performance of the improvement methods …


Programme Oriented And Institutional Oriented Approaches To Quality Assurance: New Developments And Mixed Approaches, Deirdre Lillis, Tara Ryan Aug 2008

Programme Oriented And Institutional Oriented Approaches To Quality Assurance: New Developments And Mixed Approaches, Deirdre Lillis, Tara Ryan

Articles

This paper considers the programme validation arrangements in place in one half of the Irish higher education sector. It outlines how responsibility for programme validation can be safely delegated to Institutions within a robust overarching framework for quality assurance. It compares programme validation in Institutions with self awarding status with Institutions that have their programmes validated by a national Awarding agency. The paper concludes that when programme validation in Ireland and (potentially) across Europe is examined more closely, processes that appear to be very different on the surface can be quite similar in reality. From a philosophical perspective it appears …


Extra-Large Remnant Recoil Velocities And Spins From Near-Extremal-Bowen-York-Spin Black-Hole Binaries, Sergio Dain, Carlos O. Lousto, Yosef Zlochower Jul 2008

Extra-Large Remnant Recoil Velocities And Spins From Near-Extremal-Bowen-York-Spin Black-Hole Binaries, Sergio Dain, Carlos O. Lousto, Yosef Zlochower

Articles

We evolve equal-mass, equal-spin black-hole binaries with specific spins of a/mH 0.925, the highest spins simulated thus far and nearly the largest possible for Bowen-York black holes, in a set of configurations with the spins counter-aligned and pointing in the orbital plane, which maximizes the recoil velocities of the merger remnant, as well as a configuration where the two spins point in the same direction as the orbital angular momentum, which maximizes the orbital hang-up effect and remnant spin. The coordinate radii of the individual apparent horizons in these cases are very small and the simulations require very high central …


A Measurement Of The Rate Of Type Ia Supernovae At Redshift Z ≈ 0.1 From The First Season Of The Sdss-Ii Supernova Survey, Benjamin Dilday, Richard Kessler, Joshua Frieman, Michael W. Richmond, Et Al. Jul 2008

A Measurement Of The Rate Of Type Ia Supernovae At Redshift Z ≈ 0.1 From The First Season Of The Sdss-Ii Supernova Survey, Benjamin Dilday, Richard Kessler, Joshua Frieman, Michael W. Richmond, Et Al.

Articles

We present a measurement of the rate of type Ia supernovae (SNe Ia) from the first of three seasons of data from the SDSS-II Supernova Survey. For this measurement, we include 17 SNe Ia at redshift z ≤ 0.12. Assuming a flat cosmology with m = 0.3 = 1 − , we find a volumetric SN Ia rate of [2.93+0.17 −0.04(systematic)+0.90 −0.71(statistical)]×10−5 SNe Mpc−3 h3 70 year−1, at a volumeweighted mean redshift of 0.09. This result is consistent with previous measurements of the SN Ia rate in a similar redshift range. The systematic errors are well controlled, resulting in the …


Stationary Rotating Strings As Relativistic Particle Mechanics, Kouji Ogawa, Hideki Ishihara, Hiroshi Kozaki, Hiroyuki Nakano, Shinya Saito Jul 2008

Stationary Rotating Strings As Relativistic Particle Mechanics, Kouji Ogawa, Hideki Ishihara, Hiroshi Kozaki, Hiroyuki Nakano, Shinya Saito

Articles

Stationary rotating strings can be viewed as geodesic motions in appropriate metrics on a two dimensional space. We obtain all solutions describing stationary rotating strings in flat space time strings have infinite length with various wiggly shapes. Averaged value of the string energy, the angular momentum and the linear momentum along the string are discussed.


Tidal Disruption Flares From Recoiling Supermassive Black Holes, Stefanie Komossa, David Merritt Jul 2008

Tidal Disruption Flares From Recoiling Supermassive Black Holes, Stefanie Komossa, David Merritt

Articles

Supermassive black holes ejected from galaxy nuclei by gravitational wave recoil will carry a retinue of bound stars, even in the absence of an accretion disk. We discuss the observable signatures related to these stars, with an emphasis on electromagnetic flares from stars which are tidally disrupted by the black hole. We calculate disruption rates for the bound, and the unbound, stars. The rates are smaller than, but comparable to, rates for non-recoiling black holes. A key observational consequence is the existence of powerful off-nuclear and intergalactic X-ray flares. We also discuss other observable signatures associated with the bound stars, …


The Production Of High-Quality Video For E-Learning, Eugene Mcgovern, Audrey Martin, Roy Moore Jul 2008

The Production Of High-Quality Video For E-Learning, Eugene Mcgovern, Audrey Martin, Roy Moore

Articles

As video capture, editing and transmission capabilities become more accessible, video is increasingly being considered when developing e-learning content. However, the skills required for video production are not commonly part of many e-learning developers backgrounds. This paper presents the experiences of academics from the spatial information sciences when developing high quality video content for an on-line e-learning module in Global Navigation Satellite Systems (GNSS). Video comprises one element of the module and is designed to, as far as possible, address the lack of ‘hands-on’ experience of GNSS equipment and observing procedures. The video element of the module was used by …


Children's Perspectives On Coping And Support Following Parental Separation, Ann Marie Halpenny, Sheila Greene, Diane Hogan Jul 2008

Children's Perspectives On Coping And Support Following Parental Separation, Ann Marie Halpenny, Sheila Greene, Diane Hogan

Articles

Increasingly, children experience ongoing change in family formation and structure and such fluctuation may threaten or diminish children’s feelings of security with regard to established family roles, relationships and routines. A number of studies have explored available support for children in the context of family transition, focusing in particular upon those organisations providing services to children and families. However, in order to gain more precise insight into the mechanisms through which children can best be supported, it is necessary to consult children themselves and to elicit their perspectives and responses to the changes in their family contexts. A primary aim …


A Parallel Gravitational N-Body Kernel, Simon Portegies Zwart, Stephen Mcmillan, Derek Groen, Alessia Gualandris, Michael Sipior, Willem Vermin Jul 2008

A Parallel Gravitational N-Body Kernel, Simon Portegies Zwart, Stephen Mcmillan, Derek Groen, Alessia Gualandris, Michael Sipior, Willem Vermin

Articles

We describe source code level parallelization for the kira direct gravitational Nbody integrator, the workhorse of the starlab production environment for simulating dense stellar systems. The parallelization strategy, called “j-parallelization”, involves the partition of the computational domain by distributing all particles in the system among the available processors. Partial forces on the particles to be advanced are calculated in parallel by their parent processors, and are then summed in a final global operation. Once total forces are obtained, the computing elements proceed to the computation of their particle trajectories. We report the results of timing measurements on four different parallel …

Force Measurement Methods In Telerobotic Surgery: Implications For End-Effector Manufacture, Dean Callaghan, Mark Mcgrath, Eugene Coyle Jul 2008

Force Measurement Methods In Telerobotic Surgery: Implications For End-Effector Manufacture, Dean Callaghan, Mark Mcgrath, Eugene Coyle

Articles

Haptic feedback in telesurgical applications refers to the relaying of position and force information from a remote surgical site to the surgeon in real-time during a surgical procedure. This feedback, coupled with visual information via microscopic cameras, has the potential to provide the surgeon with additional ‘feel’ for the manipulations being performed at the instrument-biological tissue interface. This increased sensitivity has many associated benefits which include, but are not limited to; minimal tissue damage, reduced recuperation periods, and less patient trauma. The inclusion of haptic feedback leads to reduction in surgeon fatigue which contributes to enhanced performance during operation. Commercially …


Artlog: Archiving The Artistic Process, Yvonne Desmond, John Mcauley, Evin Mccarthy, Ciaran Mcdonnell, Charles Pritchard, Pat Donlon Jul 2008

Artlog: Archiving The Artistic Process, Yvonne Desmond, John Mcauley, Evin Mccarthy, Ciaran Mcdonnell, Charles Pritchard, Pat Donlon

Articles

Currently there is little or no formal attempt to document the processes an Irish artist undergoes when producing a piece of art. With Artlog we aim to provide the artistic community at the Tyrone Guthrie Centre, Annaghmakerring, Co. Monaghan with a forum to not only develop their profile as an artist but also to document their work practices. In this paper we describe how Artlog came about, the relationship between the aesthetics and the importance of heritage, the approach of the project team in organising the archive and finally how interdisplinary collaboration has impacted the project.

Green Tea Extract As A Natural Antioxidant To Extend The Shelf-Life Of Fresh-Cut Lettuce, Catherine Barry-Ryan, Ana Belen Martin-Diana, Daniel Rico Jul 2008

Green Tea Extract As A Natural Antioxidant To Extend The Shelf-Life Of Fresh-Cut Lettuce, Catherine Barry-Ryan, Ana Belen Martin-Diana, Daniel Rico

Articles

Green tea extract (GT) was evaluated as a preservative treatment for fresh-cut lettuce. Different quality markers, e.g. respiration, browning, ascorbic acid and carotenoid content were evaluated. GT concentration (0.25, 0.5 and 1 g 100 mL− 1) and temperature (20 °C and 50 °C) were tested. Optimal GT treatment (0.25 g 100 mL− 1 at 20 °C) was compared with chlorine (120 ppm at 20 °C). High GT concentrations (0.5 g 100 mL− 1 and 1.0 g 100 mL− 1) maintained better prevent ascorbic acid and carotenoid loss than 0.25 g 100 mL− 1 GT and chlorine. GT increased browning of …


Assessing The Effect Of Product Variability On The Management Of The Quality Of Mushrooms (Agaricus Bisporus), Catherine Barry-Ryan, Jesus Maria Frias, Leixuri Aguirre, Helen Grogan Jul 2008

Assessing The Effect Of Product Variability On The Management Of The Quality Of Mushrooms (Agaricus Bisporus), Catherine Barry-Ryan, Jesus Maria Frias, Leixuri Aguirre, Helen Grogan

Articles

To study the shelf-life of mushrooms, over 25 batches were subjected to three storage temperatures (T) (5, 15 and 25 ◦ C) and three storage relative humidity (RH) levels (70, 80 and 90%). The effect of T and the RH on the kinetics of quality attributes of the batches was studied by measuring water activity, turgor, colour (L, a* and b* in the Hunter Scale) and weight loss of three different tissues (cap, gills and stipe) of the mushroom. Linear mixed effect models, comprising polynomial models to describe quality kinetics and allowing for batch-to-batch and inside-batch nested variabilitystructure, were built. …

Jesting Pilate, Carl E. Schneider Jul 2008

Jesting Pilate, Carl E. Schneider

Articles

I have two goals this month. First, to examine a case that's in the news. Second, to counsel skepticism in reading news accounts of cases. Recently, I was talking with an admirable scholar. He said that transplant surgeons sometimes kill potential donors to obtain their organs efficiently. He added, "This isn't just an urban legend - there's a real case in California." A little research turned up California v. Roozrokh. A little Googling found stories from several reputable news sources. Their headlines indeed intimated that a transplant surgeon had tried to kill a patient to get transplantable organs. CNN.com: …


Hubble Space Telescope Near-Infrared Snapshot Survey Of 3cr Radio Source Counterparts. Ii. An Atlas And Inventory Of The Host Galaxies, Mergers, And Companions, David J.E. Floyed, David J. Axon, Stefi A. Baum, Christopher P. O'Dea, Et Al. Jul 2008

Hubble Space Telescope Near-Infrared Snapshot Survey Of 3cr Radio Source Counterparts. Ii. An Atlas And Inventory Of The Host Galaxies, Mergers, And Companions, David J.E. Floyed, David J. Axon, Stefi A. Baum, Christopher P. O'Dea, Et Al.

Articles

We present the second part of an H-band (1.6 μm) “atlas” of z < 0.3 3CR radio galaxies, using the Hubble Space Telescope Near Infrared Camera and Multi- Object Spectrometer (HST NICMOS2). We present new imaging for 21 recently acquired sources, and host galaxy modeling for the full sample of 101 (including 11 archival) – an 87% completion rate. Two different modeling techniques are applied, following those adopted by the galaxy morphology and the quasar host galaxy communities. Results are compared, and found to be in excellent agreement, although the former breaks down in the case of strongly nucleated sources.


A Force Measurement Evaluation Tool For Telerobotic Cutting Applications: Development Of An Effective Characterization Platform, Dean Callaghan, Mark Mcgrath, Eugene Coyle Jul 2008

A Force Measurement Evaluation Tool For Telerobotic Cutting Applications: Development Of An Effective Characterization Platform, Dean Callaghan, Mark Mcgrath, Eugene Coyle

Articles

Sensorized instruments that accurately measure the interaction forces (between biological tissue and instrument endeffector) during surgical procedures offer surgeons a greater sense of immersion during minimally invasive robotic surgery. Although there is ongoing research into force measurement involving surgical graspers little corresponding effort has been carried out on the measurement of forces between scissor blades and tissue. This paper presents the design and development of a force measurement test apparatus, which will serve as a sensor characterization and evaluation platform. The primary aim of the experiments is to ascertain whether the system can differentiate between tissue samples with differing mechanical …


Diagnostic Sensitivity/Specificity Of Preattentive Vision Tests In Glaucoma, James Loughman, Peter Davison, Daniel Ian Flitcroft Jul 2008

Diagnostic Sensitivity/Specificity Of Preattentive Vision Tests In Glaucoma, James Loughman, Peter Davison, Daniel Ian Flitcroft

Articles

Purpose. Damage to the nerve fiber layer or visual pathway might be expected to reduce the efficiency with which the visual system performs analysis of the ever-changing field of vision. The purpose of this article is to provide a further analysis of previously reported data (Loughman J, Davison P, Flitcroft I, Br J Ophthalmol 2007;91:1493-98.) to: (i) determine the sensitivity and specificity of a test of preattentive vision for glaucoma detection and (ii) provide a cutoff performance level that would serve to distinguish glaucoma in early cases. Methods. Three groups of observers (glaucoma, suspects, and normals) were examined, using computer-generated …

Drawing on the ‘Energy Descent Action Plan’ he developed at Kinsale, Rob Hopkins and his team launched Transition Town Totnes (in the UK) one and a half years ago. 64 recognised transition communities and 600 other groups (and counting) are now in communication with Rob’s team to launch their versions of this initiative in their communities worldwide.1 The Transition Ireland Network is coordinated by Davie Philip of Cultivate and several transition initiatives are underway here.


Straddling The Civil-Criminal Divide: A Bifurcated Approach To Understanding The Nature Of Immigration Removal Proceedings, Peter L. Markowitz Jul 2008

Straddling The Civil-Criminal Divide: A Bifurcated Approach To Understanding The Nature Of Immigration Removal Proceedings, Peter L. Markowitz

Articles

The article advocates for reclassifying immigration removal proceedings, distinguishing between exclusion and expulsion. It argues that while exclusion should remain a civil process, expulsion, particularly for lawful permanent residents, should be treated as a criminal matter due to its punitive nature and severe consequences. This bifurcated approach aims to align legal procedures with the reality of the impact on individuals and ensure constitutional protections.


Rethinking Tax Nexus And Apportionment: Voice, Exit, And The Dormant Commerce Clause, Edward A. Zelinsky Jul 2008

Rethinking Tax Nexus And Apportionment: Voice, Exit, And The Dormant Commerce Clause, Edward A. Zelinsky

Articles

The dormant Commerce Clause concept of tax nexus is best understood as a rough, but serviceable, proxy for the taxpayer's standing in the political process. This perspective leads me to defend Quill Corporation v. North Dakota and the much maligned physical presence test for tax nexus. As a matter of legislative policy, the critics of this test may be correct. However, as a matter of constitutional law, the courts should adhere to an expanded physical presence standard as Congress crafts for the long term broader nexus rules based on economic presence. Taxation is an inherently and irreducibly political matter. An …

A New Method To Integrate (2+1)-Wave Equations With Dirac’S Delta Functions As Sources, Carlos O. Lousto, Hiroyuki Nakano Jun 2008

A New Method To Integrate (2+1)-Wave Equations With Dirac’S Delta Functions As Sources, Carlos O. Lousto, Hiroyuki Nakano

Articles

Unlike in the Schwarzschild black hole background, gravitational perturbations in a Kerr black hole background can not be decomposed into simple tensor harmonics in the time domain. Here, we make mode decompositions only in the azimuthal direction. As a first step, we discuss the resulting (2+1)-dimensional Klein-Gordon differential equation for scalar perturbations with a two dimensional Dirac’s -function as a source representing a point particle orbiting a much larger black hole. To make this equation amenable for numerical integrations we explicitly remove analytically the singular behavior of the source and compute a global, well behaved, effective source for the corresponding …


Locked Out: The 1905 Dispute Between The Agibsltu And The Master Builders Association, John Hogan Jun 2008

Locked Out: The 1905 Dispute Between The Agibsltu And The Master Builders Association, John Hogan

Articles

When the issue of a lockout in Dublin comes up for discussion, invariably, the Great Lockout of 1913 springs to mind. This event, in both its scale 4 and scope, has tended to crowd out the examination of all other lockouts that occurred in the city in the early years of the 20th century. Beside the Great Lockout contemporary industrial disputes have tended to pale in comparison. As a result of its magnitude, the 1913 lockout has provided a vast reservoir of research material that has been heavily mined. However, this concentration on 1913 could lead to the erroneous conclusion …
